Now it is time to take control of your robot. We will be using the Adafruit Bluefruit LE Connect app. Go ahead and download it on your preferred device.
Load up the Bluefruit LE Connect app, and the first thing you will see is a list of available Bluetooth devices to connect to. Find the one that says Adafruit Formula E Racer, and tap the Connect button.
Here's what it looks like on the iPad version:
Once you connect, you will see a whole bunch of device information. At the bottom of the app, tap the Controller button.
On the next screen, you will see some advanced features of the app. For now, click the Control Pad link.
The Control Pad should load up, presenting four arrow keys, four assignable buttons, and a small readout for streaming data.
Make sure your race car is unplugged from USB (the LiPoly battery will provide power), and that the AA battery pack is turned on.
Then, go ahead and use the arrows to drive your rover. Be careful, this little guy is fast! Be sure to place it on the floor first!
